ESS1–3
Explain how internal and external sources of heat (energy) fuel geologic processes (e.g., rock cycle, plate tectonics, sea floor spreading);
3a explaining how heat (produced by friction, radioactive decay and pressure) affects the Rock Cycle;
3b explaining how convection circulations of the earths mantle initiate the movement of the crustal plates which then cause plate movement and seismic activity.
3c investigating and using evidence to explain that conservation in the amount of earth materials occurs during the Rock Cycle
Context of Lesson:(Summary)
Students just finished a lesson on the Earths layers and this second lesson will draw off that. Rocks are all around us. In fact, thick layers of rock make up the Earth. Rocks are composed of one or more minerals and scientists observe rocks because rocks contain clues to the Earth's history, such as dinosaurs and other life forms that have existed. The Earth is continually moving and so are rocks. Rocks are heated, compressed and weathered to form new rocks. This process is called the rock cycle. Studying the rock cycle is one component to understanding the mechanism of plate tectonics. The movement of tectonic plates causes change in the production and destruction of metamorpic, sedimentary and igneous rocks.
Students will view a multimedia version of the Dynamic Earth by the Smithsonian National Museum of Natural History where they will discover the history of the Earth through rocks. Then, they will participate in an interactive lesson where they will learn how rocks are formed, how they can be identified, and how they they change over time and what processes cause these changes. This interactive provides great visualization of rocks up close. This interactive will also assess students knowledge on Rocks with multiple choice questions at the end of each section.
Once students complete the days lesson, they will be instructed to enter key clues into their detective journal that is evidence for plate tectonics based on the rock cycle.
Objectives:
Students will learn:
how rocks change.(Rock cycle)
what rocks are made from.
what the (3) types of rocks are.
how one rock forms into another
the commonality of each rock type in the Earth's crust.
origin, texture and composition of Igneous, sedimentary and metamorphic rocks.
how rock provide evidence for plate tectonic theory.

Instruction:
Opening:
Students just finished learning about the Earth's interior. I will probe students to answering questions relating to the Earth's crust, mantle and core leading to concepts about plate tectonics. Much material wil be covered in this Lesson. The Agenda will be posted on board which will include: The story continues, more evidence, rock cycle, Smithsonian website, learner interactive and homework assignment. Once again, stressing the importance of a putting the pieces together in order to solve the plate tectonics mystery will be discussed.
The lesson will wrap up by informing students that studying rocks and the rock cycle is another piece of the puzzle for studying plate tectonics. Homework assignment will be given as well as written on the board. Students will add evidence for plate tectonics from studying rocks in their detective handbook journals.
